Are fine-needle aspiration biopsy-derived cell blocks a useful surrogate for tissue samples in breast cancer?

Aims: The diagnosis of breast cancer (BC) is based on clinical examination in combination with imaging, and confirmed by pathological assessment of core needle biopsy or fine-needle aspiration biopsy (FNAB). The biological profile of the lesion is needed to define the prognosis and establish therapy. Given the importance of an early and minimally invasive diagnosis, we aimed to verify whether the biological features detected in FNAB-derived cytological material reflect the biological characteristics of surgical samples.

Activity of Eribulin in a Primary Culture of Well-Differentiated/Dedifferentiated Adipocytic Sarcoma.

Eribulin mesylate is a novel, non-taxane, synthetic microtubule inhibitor showing antitumor activity in a wide range of tumors including soft tissue sarcomas (STS). Eribulin has been recently approved for the treatment of metastatic liposarcoma (LPS) patients previously treated with anthracyclines. This work investigated the mechanism of action of this innovative antitubulin agent in well-differentiated/dedifferentiated LPS (ALT/DDLPS) which represents one of the most common adipocytic sarcoma histotypes.

Progesterone receptor status and clinical outcome in breast cancer patients with estrogen receptor-positive locoregional recurrence.

Aims And Background: The aim of this retrospective multicenter study was to evaluate the impact of progesterone receptor (PgR) loss on locoregional recurrence in patients with estrogen receptor (ER)-positive primary breast cancer and ER-positive locoregional recurrence.

Patients And Methods: Eight Italian oncology centers collected data from consecutive patients with ER-positive breast cancer and a subsequent ER-positive locoregional recurrence.

Results: Data were available for 265 patients diagnosed with breast cancer between 1990 and 2009.

Albumin nanocapsules containing fenretinide: pre-clinical evaluation of cytotoxic activity in experimental models of human non-small cell lung cancer.

Unlabelled: The present study deals with the preparation of albumin nanocapsules containing fenretinide and their evaluation in experimental models of human non-small cell lung cancer. These nanocapsules showed enhanced antitumor activity with respect to free fenretinide due to the solubilization effect of albumin on the hydrophobic drug, known to improve bioavailability. The high expression of caveolin-1 on the A549 cell surface further enhanced the antitumor activity of the nanoencapsulated fenretinide.
